Patent GB-172001-A (GB)
Abstract: 172,001. Bergeon, P. Nov. 25, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Heating by electricity.-A vessel B through which the water or gas to be heated is circulated surrounds a water chamber A connected to a compensating-tank H and fitted with electrodes comprising non-oxidable plates E insulated from each other and consolidated together, and an air outlet pipe I. The tank H is fitted with a safetyvalve S, a blow-off cock P, a pressure gauge M, and a filling cock R. If steam is generated in the chamber A, the water therein is forced back into the tank H and the electrodes are now completely immersed, so that the, current supply is automatically regulated to maintain a certain temperature according to the pressure in the chamber A. The pressure in the chamber A may be varied by raising or lowering the tank H or by increasing the pressure or producing a vacuum therein. For heating gas, the heat-transmitting surface is increased by means of ribs or tubes.

Abstract: 434,553. Thermal switches. SATCHWELL, L. Farnham Road, Slough, Bucking- hamshire. June 12, 1934, No. 17410. [Class 38 (v)] A thermostat of the panding rod or tube type for controlling the temperature of electricallyheated liquids is provided with an additional safety device in the form of a fusible element adapted to melt and cut off the current should the contacts of the thermostat stick and allow a dangerous temperature to develop. Fig. 2 shows one form with an expanding tube 4 and non-expanding rod 3 carrying a screw 7 bearing on a switch blade 9 carrying a contact 6 normally engaging a fixed contact 14. Expansion of the tube 4 causes separation of the contacts, a permanent magnet 17 and armature 18 providing a quick action. In series with the contacts 14, 6 and blade 9 is a spring 10 which is held to a contact block 13 by fusible metal 16. When the metal 16 fuses owing to heat conducted from the heating vessel the spring 10 moves of its own resiliency away from the contact 13. In a modification, Fig. 3 (not shown), the spring 10 carries a rod which is held fused to a projection on the base. In this modification the current does not pass through the fusible member.

Abstract: 626,132. Television. PHILIPS LAMPS, Ltd. June 14, 1946, No. 18031. Convention date, June 15, 1945. [Class 40 (iii)] In a television &c. system in which the frame synchronizing pulses are slotted at twice the line frequency frame synchronization at the receiver is effected at the end of the first slotted period. The combined synchronizing pulse train comprising line pulses Sz and frame pulses Sb, slotted at So at twice the repetition rate of the line pulses, is applied to a circuit of the type shown in Fig. 9 which has a response characteristic as shown in Fig. 3, and provides across the output terminals 3, 4 thereof a pulse train such as shown in Fig. 2. This pulse train controls the synchronization of the framescanning generator which is arranged to be triggered at the level A. With this arrangement, the instant of synchronization t1, which is determined by the end of the first frame slotted period, is said to be independent of amplitude variation of the frame pulses. Instead of the circuit of Fig. 9, other R.C. networks, Figs. 10, 11, 12 (not shown), which have response characteristics similar to that shown in Fig. 3, may be employed.

Abstract: 121,191. Feldenheimer, W. Dec. 6, 1917. Wet-separating.-Relates to a process for cleaning clay by treating an aqueous suspension first in one vessel with a deflocculator, .such as weak sodium carbonate, to enable impurities to settle out, and then in another vessel with a flocculator, such as alum solution, which causes the clay to settle, as described in Specification 106,890. According to the present invention, the flocculating- reagent is added so slowly, or in such total quantity relatively to the quantity of the deflocculator, as to cause flocculation or coagulation of the clay, but not rapid sedimentation. By this means, there is obtained a separation from the clay in suspension of impurities not ordinarily separated therefrom by the deflocculator alone. With certain deflocculators, such as a weak solution of sodium carbonate, a strong solution of the same material may be used as a flocculator. When sodium carbonate is employed, discoloration of the clay may be prevented by the addition of ultramarine prior to the addition of the flocculating- agent. Various flocculating and deflocculating agents are described.

Abstract: 1,066,939. Colour television. MULLARD Ltd. March 3, 1966 [April 29, 1965], No. 18175/65. Addition to 1,005,696. Heading H4F. A transmitter for producing a chrominance carrier signal as described in Specification, 1,005,696, which comprises a. first component Á = a(R - Y) + a(B - Y) and a second quadrature component p = b(R - Y) - b(BY) which is reversed in phase (- p) in alternate lines, also includes means for producing between lines a synchronizing carrier " burst " signal B1 which is switched to a quadrature phase position B2 following alternate lines. The phase, of the signal B1 equals that of one of the components Á, p or the inversion thereof. As illustrated the phase of signal B1 corresponds to the inverse of the phase of component Á whereby the mean phase of B1 and B2 coincides with the axis, - (B - Y), occupied by the " burst " in conventional N.T.S.C. and P.A.L. systems. In alternative arrangements the mean phase may coincide with the + (B - Y), + (R - Y) or - (R - Y) axis. The "` burst " signal is produced by pulses from a source (4), Fig. 2 (not shown), which are applied to the quadrature modulators (1) and (2) via a switch (5) which is'changed over at line rate. The" burst "signals are established in the appropriate quadrant by choice of polarity of the pulses in relation to that of the colour modulating signal. The chrominance signal is modulated on a main carrier, -which carries a luminance signal, in modulator (3).
